Abstract

A process for making a soft touch outer surface for an object includes the steps of first providing a core (44) to receive a soft touch outer surface thereon and providing a mold member (40, 42) having a mold cavity (50). The core (14) is then placed inside the mold cavity (50). A low durometer elastomer, having a Shore 00 hardness of 70 or less, or a low density foamed plastic, having a specific gravity of specific gravity between 0.1 and 0.7 is injected into the mold cavity (50) to surround the core (44) in 360 degrees to provide a predetermined thickness of a cushioning layer. The core (44), with cushioning layer (52) thereon, is demolded from the mold (40, 42) by which it was formed. The outer surface of the cushioning layer is then covered with a finish layer (56).
